UPLIFT 900 Four-Leg Adjustable-Height Standing Desk Base

item#: UPL940

It's no secret that standing while you work is the key to a healthier and happier day at the office. However, if you have a larger desktop that you can't part with, a conference table that you want to use for standing meetings, or just need more stability than a two-leg sit-stand desk can offer, your options have been limited. But thanks to the UPLIFT 900 Four-Leg Adjustable-Height Standing Desk Base, that's no longer the case! This four-leg sit-stand ergonomic desk base was designed by a Certified Professional Ergonomist to provide the absolute maximum in stability while still allowing you to enjoy the health benefits that come with standing at work! With a motor in each leg, you will experience lightning-fast, whisper-quiet height adjustment from sitting to standing with the push of a button. Best of all, you don't have to throw away that antique, hand-carved desktop, since this frame-only model can turn any desk into a standing desk. Or, order a full desk with one of our GREENGUARD certified laminates or real wood desktops. With more flexibility than ever before, an UPLIFT Desk is not just the desk for everyone, it's also the desk for you.


Check out why we think UPLIFT is the #1 standing desk solution on the market. We're not the only ones who think so, either. See who else is using UPLIFT Desks and find out why UPLIFT is priced so low. We want you to ask us ''How do you sell this for such a great price?''

Base Color

Choose from three frame color options: black, gray, or white. The frame has a generous height range of 23.5"-49" (not including desktop thickness) and lifts up to 710 lbs.

Finding the right height preferences for you at your new adjustable height desk can be revitalizing. Another benefit of using a standing desk is the ability to sit in a more ergo-friendly position for your body, ideally with your keyboard and mouse on your lap or within your Neutral Reach Zone. This is different for everyone, but UPLIFT's height range of 24.5'' - 50.5'' means that it will work for 99% of the population!

Most height adjustable desks on the market are stabilized with a two-stage frame, which has lower minimum and maximum heights, limiting your ability to adjust to your perfect height if you're taller or shorter than average. UPLIFT's three-stage frame goes both lower and higher, giving you the ability to adjust your desk height even more so you can keep working comfortably whether sitting or standing.

Our competitors offer height extensions at a premium, while ours comes standard when you choose an UPLIFT adjustable height desk. Invest in a desk that will uplift your office for years to come, helping you and your coworkers to reach the highest peaks of productivity.

Keypad

UPLIFT Desks come standard with a basic Push and Hold Two Button Up/Down Keypad, or you can upgrade to the Advanced Keypad with 4 Memory Positions and Digital Height Display. Its digital readout allows you to make precision adjustments to get your desk to exactly the height you need, then auto-dims to save power. Once you find the perfect sitting and standing heights, four programmable memory presets allow you to save those and then return to them by simply pressing and holding one button.

CPU Holder

When using a sit-stand desk, we recommend mounting your computer beneath your desktop to prevent cables from being stretched and pulled out of their ports when moving the desk from sitting to standing positions. An UPLIFT CPU Holder allows you to securely attach your computer tower to the bottom of your desktop to free up desk space.

Please note that mounting options are limited when pairing this with a 48" wide desktop. Please refer to our blog article, which shows the possible configurations. If you still have questions, please give us a call and we would be happy to discuss it with you!

Keyboard Tray

An ergonomic keyboard tray gives you the freedom to adjust the height and tilt of your keyboard independently from the desk and also relieves the strain caused by over-reaching to type. The UPLIFT Large Keyboard Tray comes with one, 27'' wide surface for your keyboard and mouse to sit side-by-side. For those who prefer more flexibility, the UPLIFT Switch Keyboard Tray comes with two surfaces: a 19.75'' wide platform for the keyboard and a separate 9'' diameter surface for the mouse. The mouse platform can easily move to the left or right side for ambidextrous mousing, and is also depth adjustable.

Add an UPLIFT Track Spacer to either keyboard tray to allow you to mount the track over the center crossbar rails on your desk, allowing for better desktop support on wide desktops and full keyboard tray retraction on 24'' deep desktops.

Experts recommend standing at least 2-4 hours per workday, and the reasons why are clear. Standing burns 50 more calories per hour than sitting; it also fights the devastating long-term health effects that come with a sedentary lifestyle. More people are making the leap to standing desks than ever before, but most standing desks use a two-leg design that performs differently than a traditional four-leg sitting-only desk. Fortunately, you no longer have to choose between the two styles. With the UPLIFT 900 Four-Leg Adjustable-Height Standing Desk Base, you will get unparalleled stability and unsurpassed support, even at a standing height.

This desk base's unique four-leg design incorporates no crossbar or long brackets, allowing you to place the legs wherever they would make the most sense on your desktop. With a motor in each leg and a weight capacity of over 700 lbs, this electric sit-stand desk frame is capable of lifting practically any surface in a matter of seconds. Additionally, this base will work with conference tables and other large surfaces, allowing you to foster creativity and collaboration through standing meetings and brainstorming sessions. Height-adjustment is easy with the standard up/down keypad, or you can upgrade to the Advanced Digital Memory Keypad for easy adjustment to the heights you use the most.

Of course, while this four-leg sit-stand desk base is the foundation of your brand-new ergonomic set-up, its also just the beginning. With a wide range of ergonomic accessories and wire management options available, you can build the perfect workstation. And, thanks to the free-standing design of the legs, there will be plenty of space underneath the desk for you to mount your new accessories in a way that makes sense for you. The options are virtually unlimited, so stop waiting and stand for a healthier day with the UPLIFT 900 Four-Leg Adjustable-Height Standing Desk Base.

*Because the brackets allow for custom placement of the legs on your desktop, you will need to make sure the desktop you put on this base is stiff and not prone to bending or sagging. For desks up to 72" wide (and 30" deep), we suggest at least a 1" thick real wood or high quality laminate, similar to the GREENGUARD laminate we use on our full four leg desk. For desks larger than this, we recommend a 1.5" or thicker top.
